Staten Island Advance/Elise McIntoshRichmond resident Vincenzo Roveccio says he was surprised by how much his wife loved being pregnant.

From conception to birth, there are so many interesting observations parents-to-be can make when witnessing the miracle of life unfold before their very eyes. To see what stood out in men’s minds, we polled a few fathers about what they found surprising during their partners’ pregnancies.

Vincenzo Roveccio said he was taken aback by how well his wife took to pregnancy.

“It was fantastic. There was no problem at all. My wife was always in good humor,” said the Richmond resident, a native of Sicily. In fact, after the couple’s son was born, his wife told him how much she missed her big, round belly, Roveccio recalls.

Douglas Spano couldn’t believe how different his wife’s stomach looked during the pregnancies of their two children. For their first-born, a boy, the baby bump “was all out in front and it was symmetrical,” the Westerleigh resident remembered. But, during her pregnancy with the couple’s daughter, his wife’s protruding belly was lower and rounder, he said.

Spano also couldn’t believe how much her feet and ankles swelled — and, how, he quickly added, “she lost every bit of that weight,” especially after the birth of their son, Anthony, who weighed 10 pounds, 11 ounces, when he was born.

Jim Manning of Tottenville said he was surprised by how much his wife, Yvonne, could do while carrying their child. She ran a household, worked as a school teacher and still handled the challenges of pregnancy without a complaint.

“She was tough as nails,” he said about his wife of 23 years, who died four years ago.

It was all the preparations he and his wife had to make in the months leading up to the birth of their son — “getting all our ducks in a row” — Tommy Murgia remembers.

“It’s a beautiful experience,” the Port Richmond dad said, adding, “That’s why we did it again.”
